Cylinder Heads Street/Strip 427 Tall Deck
What is the Better Head to Run Open Or Closed for a Tall Deck 427 BBC?
I've been looking towards the Oval Port 3904390 98 CC BBC Heads.
Anyone have any Advice on which is best to use?
Will be running a Dual Carb Tunnel Ram,4.25 Stroke Crank,Used to the SBC Scene but want to Move up to the Big Block now.
I've got a 91' Chevy S-10 that I would like to Build up and Run Street/Strip.
Thanks, all Help is Greatly Appreciated.

I would have to agree with the above reply, you need more air to feed that 496 than those closed chambered peanut port heads can deliver, those heads are more suited to smaller CI motors like a 396 or 427. Not saying they wouldn't work but it would be like trying to cram a gallon of gas thru a straw.
Invested in some good retangular port heads with open chambers.
Goodluck, Charles
